If you go into this movie with expectations based off of the trailers, as I did, you will find yourself surprised by the tone of the movie. While the trailers make this appear like a contemporary, dark thriller, this movie looks back to thrillers of earlier decades. The dialogue is light, but the acting carries depth. The score, to my novice ear, hearkens back to Hitchcock.
Garrett Hedlund and Oscar Isaac both deliver an excellent performance. They play well off of each other and tell a story of ambiguity, not in the sense that what the characters do is ambiguous - they are both clearly in the wrong for different reasons - but in the sense that viewers can suspend their judgment as they observe the action.
With all of the negative reviews I've seen on here, I was expecting something "2edgy4me" but I ended up with a pleasant surprise. This movie was well worth the wait after about a year since its presentation at Tribeca.
